Contratiempo aka The Invisible Guest (2016)
The writer of
Julia's Eyes (2010), Oriol Paulo's 2nd feature film after 2012's awesome Spanish thriller
The Body. Though not as great as his earlier works & you may get the 'twist' halfway through but still this is a pretty well-crafted, intense 'who or how-done-it' style another good Spanish thriller.
Recommended.
>>: B+
